PopSci reports:
"Designed by Massachusetts art duo Harries/Heder, the SunFlowers are an art exhibit at heart, and stand over 30 feet tall. They collect power from the sun by day, and use that energy to power their blue LEDs at night. Up to 15 kilowatts of surplus power is sent back to the grid as payment for any maintenance fees the SunFlowers incur." See full article.
